,14 Claims. (01. 153-21 This invention relates in particular to a machine for feeding and applying plastic necks to metallic collapsible tube bodies,-- although in its broader aspects the invention contemplates means for supporting and conveying any of various articles such as collapsible tubes in succession past one or more stations where a part, e. g., a plastic neck, is fed to and secured upon each article in one or more operations.

It has been proposed to form a socket orrecess in one end of the body portion of a metallic collapsible tube, insert a threaded neck of plastic material in said socket and swage or squeeze or press the walls of the socket around the neck so as to secure the latter by a firm, liquid-tight joint to the tube body.

One object of the invention is to provide a machine of the general character described which shall comprise a novel and improved construction, combination and arrangement of a support for articles such as collapsible tubes formed of ductile material and having a socket or other portion for attachment thereto of another part such as a neck, means for moving said support to convey said articles in succession past one or more stations, means for feeding and applying one of said parts to said portion of each tube, and means for swaging, squeezing or pressing the material of said articles around said parts to secure the parts on said articles,-whereby such parts can be applied to such articles rapidly and relatively inexpensively. I

In many cases, especially in applying plastic necks to metallic collapsible tubes, a plurality of operations are required in pressing the material of the articles around the parts being secured thereto, and therefore another object of my invention is to provide a machine of the character above described which shall include a plurality of tools or parts or sets of parts such as dies, each to perform one of said operations, and a common support and actuator therefor arranged in such relation to means for conveying said articles, that one of said operations shall be performed upon one of said articles at the same time that the other operation is being executed upon a preceding or a succeeding article as the case may be, whereby speed and simplicity of operation shall be attained.

It is desirable in such machines that the article conveyor include article holders which move in an endless path or in cycles past said stations, and each article after one of said parts or necks has been secured thereon must be removed from its holder before the latter is returned to the sta- 2 tion at which said parts are supplied. Should an article having one of said necks or parts attached, thereto be presented on the conveyor at said part-v feeding station, jamming or injury of parts of the machine might occur upon feeding of another part or neck and as a result of operation ofv the aforesaid tools or dies. Therefore, another objectof the invention is to provide novel and improved means for controlling the feeding of said parts or necks such that feeding ofv the parts shall be prevented or interrupted in case an article having one of said parts thereon inadvertently is presented at said station.

Another object is to provide a novel, improved, simple and reliable construction, combination and arrangement of a device for pushing a part such as a plastic neck into proper relation to a portion of an article suchv as a socket on the end ofa collapsible tube, means for pressing said portion of said articleand said part into tight contact with each other, and common means for operating said devices in succession in a continuous operation. 1

spindles or supports C for articles such as collapsible tubes D. The carrier is: rrrova l' ile so -as"- to convey the articles D in a predetermined path. with a step-by-step or intermittent motion and to present them in succession at two operating stations. Each article or tube D has a; portion, specifically an annular socket l" at oneend, in which apartsuch as-a plasti'c' ne'ck" Z'is to besecured'. I 7

At one of said operatingstations is apparatus E' for feeding the parts' or necks; and mechanism F for applyingthe parts ornecks'to the tubes D. At the other station is an-operating element G for performing another operation onthe articlesor tubes afterthey have operated-*upon at the first station. Y I

The articles or tubes to :be'operated upon are placed upon and removed fronrthe' holders 6 by hand.

More specifically; the carrier: 3 comprises a turret disc which-is mounted on a shaft 3 which in turn is journaled in the frame'A to rotate on a: horizontal axis, and the dead spindles pro .ie'ct' horizontally from one face of the disc in circumferentially spaced relation. The carrier disc is rotated with an intermittent or step-bystep motion in any'suitable manner as by a Geneva gear H whi h is driven through a trainof gearsI'from a drive-shaft K.

The feedingapparatus E "comprises a vertica-P chute 4 in which the necks 2 are arranged in superposed relation so that they will descend bygravity in the chute. The chute has a horizontally disposed lower end which isprovi'ded with on registers with arr opening 6 in the housing Tir'rwhichthe devices F are mounted. A spring detent 8 normally prevents discharge of the necks through the openings 5 and 6 but upon application or s-u flicient pressure on the lowermost" neck to overcome the spring-resistance ofthe-detent 8; the detent will be displacedand permit the lowermost neck to pass from the chute. For ejecting thenecks from the chute, we have utilized a reciprocating ejector bar MI which normallyis disposed above the lowermost; neck: in. the chute 4 A'tensiorr. spring: I=.I normally influences: the. ejector: bar downwardly to ejecta neck 2 from the chute; but movement ofthe: ejectorbar controlled by a lever I 2 which is pivotally. mounted; at I3 inter mediate its.- endson the. frame A and; has apin and slot: connection I 4. atone end. withthe ejector bar I0. The other end of the lever I2 carries a roller l5 which follows a cam L6 that is mount ed on a shaft H which has a sprocket lflith'at isconnected by a chain I9 to a sprocketZiTthat is carriedb'y-the stubshaft 2| of the gear trainI.

The camr I6 and the Geneva gear Hare driven in timed relation to each otherso that at sea step of movement one of the spindles C is presented at the station to which the necks are fed, and at the end of said step of movement or in the interval between steps of movement the cam I6 permits the ejector bar In to be drawn downwardly by the spring, II. with a snap action. so as, to strike the lowermost-neck; 2 and drive it past the detent 8" out of the chute and to. the neck-applying device F. These neck applying devices F include a tubular member 22 is longitudinally reciprocable in the housifrrgs..T-"ti:a;-nsversely of the dischargeopenings 5 r and 6 of. the chute 4.. The member 22 has a lateralpassage 23" through which each neck 2 may ed a carrier disc B which has a plurality of dead;

.passinto. member, and a pair of diametrically; opposite. spring arms 24 are mounted in slots 24!] in the member 22 to grip and hold the neck as it is ejected from the chute as clearly shown-in-Figures 7 to 10 inclusive, the passage 25 and spring arms 24 thus serving as a holder for the necks. A guide block 220 secured inthe housing I is arrangeri'in a groove Z21" in the member; 22 to prevent rotation of the latter. The member" 22; has at flange to abut the; housing "I" fbr limiting movementof said member in the direction towardfthe carrier B andf'thisr fiange' has openings whreach ofiwhi'ch one end of one arm'2 i is securedby a set screw 27'; The tubular member is'lo'cate'd' so as tobe'coaxial or in direct alinementwith the spindle C as the latter-stops at the first station.

I'longitudinally slidablyimounted': within the tu.-- bul'armember Z2 is a push .rod' 28' .whichnorma'l'l'y is'disposedi at the side of the passagezt opposite the carrier B; The tubular. member and. the push red are relatively movable longitudinally 's'uch movement being, limited bya set screw 29. the member '22. which has its endiin a slot. tlii'n the. push rod; A compression spring 3I is interposed between the tub ularmemherfl'ancf the pushrod for holding. them in. normal relationas. shown inFi'gure. 4 and; to causecth'em initially to.- move together and permit relatiize movement. thereof. p i g The push. rocl hasv one/end. connected toa.

rated in any suitable manner. The interior surface of the neck is also serrated as at 450.

The outer end of the tubular member 22 comprises a die which has a surface 41 so shaped as to press the outer walls'of the socket i of the collapsible tube around the basal flange st of the neck 2.

In operation of the machine so far described, the operator applies a collapsibletube to each spindle just prior'to the movement of that spindle to the first station for application of the neck. During a step of movement of the carrier, the ejector bar In of the neck feeding apparatus E will have forced a neck into the tubular member 22 as shown in Figure 4. When the carrier has moved one of the spindles C with its collapsible tube D into alinement with the tubular member 22, the actuator 32 will be moved to slide the push rod 28 toward the tube D. At the same time the tubular member 22 will be moved with the push rod until the surface 4? of the tubular member engages the edge of the outer wall of the socket l of the collapsible tube. Thereupon movement of the member 22 will be interrupted but the push rod will continue to move and force the neck into the socket I as shown in Figure 5. The actuator 32 will continue to move in the same direction so that pressure through the spring 3| will be exerted on the tubular member suificient to cause the surface 41 to swage or press the wall of the socket I around the basal flange 46 of the neck as shown in Figures 5 and 9.- Thereupon the actuator 32 will be moved in the other direction and the carrier B will start another step of movement and convey the tube D with the neck thereon to the next station where the tube will be operated upon by the element G.

This element comprises a tube 43 mounted in the actuator 32. Specifically, the actuator has an opening 49 therethrough in which a flanged bushing 50 is secured by a set screw 5!. The tube 48 is slidably mounted in an opening in the bushing and is adjustable inwardly and outwardly of said opening by a screw 52. The outer end of the tube 48 has a die surface 53 to compress the metal of the wall of the socket i into tight contact with the basal flange of the neck, particularly to force the metal into the serrations in the flange and to provide a non-rotative, water tight joint between the neck and the tube, as shown in Figures 11 and 12.

The die 53 is brought into engagement with one tube simultaneously with the application of the neck to the next succeeding tube, as shown in Figure 6. The desired adjustments to effect proper compression of the metal of the collapsible tube by the die 53 may be efiected by movement of the tube 48 in the bushing 55 through adjustment of the screw 52.

It will be seen by those skilled in the art that should the operator fail to remove a tube from its spindle C after the neck has been applied, the tube might be presented at the first station and feeding of another neck and operation of the neck applying device F might result in jamming or injury to parts of the machine. To overcome this possibility we propose to utilize means for preventing feeding of a neck from the chute 4 in case a tube having a neck already applied thereto is presented at the first station.

For this purpose we have shown an electromagnetically operated device for holding the ejector bar l0 against neck-ejecting movement and to release said bar for normal operation as a tube having a neck thereon approaches and passes the first station respectively. The device comprises a solenoid which has a re'ciprocable core 56 to which is pivotally connected at 51 one end of a link 58 which has a slot to receive the pin M on the ejector bar Ill. The slot of the link 58 is of such length that when the core 55 of the solenoid is at its lowermost position as shown in Figure '7 the lever I2 and the ejector bar It are free for normal operation, while when the core 56 is drawn upwardly as shownby dot and dash lines in Figure '7 the link 58 will prevent swinging of the lever 12 and downward movement of the ejector bar ID. A spring 59 normally draws the core 56 downwardly so that the pin 51 engages a fixed stop 60.

For controlling energization and deenergization of the solenoid 55, we propose to locate a normally open electric switch 6| on a bracket 62 on the frame of the machine so that the switch will be closed by contact therewith of the plastic neck of a collapsible tube on a spindle which is approaching the first station, and connect said switch in circuit with a holding relay I2 and a normally closed electric switch 63 so that the solenoid 55 will be energized as said collapsible tube approaches the first station and will be held energized until the tube has passed said station, after which the solenoid will be deenergized by opening of the switch 63 as by engagement therewith of the spindle C. I

More specifically, the switch 6| comprises a casing 64 in which is a contact block 65 mounted on a reciprocable rod 66 Which has a hinged connection '6! with a lever 68. The block cooperates with two fixed contact studs 69 and is normally held out of contact therewith by a spring 10. The switch is so located on the bracket 62 that normally the lever 58 will be untouched and the switch will remain open. However, upon approach of a tube having a neck, the neck will press the lever 68 so as to cause contact between the contact block 65 and the studs 69 and thus close the switch.

The switch 63 is similar in structure and comprises a casing 13 in which is a contact block M carried by a switch rod which is reciprocable in the casing and is normally influenced by a spring 16 to hold'the contact block 14 in contact with fixed studs 11. A lever 18 is pivotally mounted intermediate its ends at 19 on the casing and has one end hinged at 30 to the switch rod 15 and its other end provided with a roller 8| which is disposed in the path of movement of the spindles C. Normally the switch is closed but when a spindle C passes beneath the roller 8| the switch block 14 is pulled out of contact with-the studs 11 to open the switch.

The two switches 6| and 63 are connected in circuit with a holding relay 1'2 of known construction as shown in Figure 15. This relay comprises a solenoid 82 and a reciprocable armature 83 which cooperates with two contacts 84 and 85. As will be seen from the drawing, the switches El and 63, the solenoid 55 and the holding relay 12 are connected in circuit so that normally the solenoid is deenergized. When the switch BI is closed, the holding relay is operated to close and hold closed the circuit through the solenoid 55 and also to maintain the circuit through its own solenoid 82. Then when the switch 53 is opened the circuit is broken and the holding relay sole noid 82 is deenergized so that its armature 83 is actuated by a spring 8521s usual to break the circuit through the solenoid 55. I

As above indicated, when the switch Bl is closedthe consequent energization of the solenoid 55 results in :a holdin of the ejector bar iii-oi the neck feeding apparatus against 'feeding'operation, while when the switch 63 :is opened; consequent deenergization of the solenoid 55 will release the ejector bar l for normal operation.

While we have shown and described the inven .tion as embodied in certain details of structure, it will be understood that many changes in the structure of the'machine maybe made withintthe spirit and scope of theinvention.
